Title: Fluidized layer combustion device equipped with fluidized layer height control device
Inventor: NONAKA KIMIHIRO
IPC: F23C10/02
Filed: 1988-02-23
Abstract: PURPOSE:To suppress the generation of a slagging phenomenon and to construct a compact fluidized layer height control device by providing the fluidized layer section of a layer height control device with a plate shaped porous internal. CONSTITUTION:A layer height control device 6 and the fluidized layer section 17a and 17 of a fluidized layer furnace 1 are connected by a connecting pipe 7, and a medium 3 is drawn out from the fluidized layer furnace 1 by this connecting pipe 7. The layer height control device 6 consists of a diffusion plate 8, internal 9 above it, and medium drawing pipe 10. The air which fluidizes the medium is led from a pipe passage 4a to an air chamber 16 under the diffusion plate 8 and then the air goes as an exhaust gas 11 from the upper section of the device to an air tower 1a and is discharged with the combustion exhaust gas 12 out of the system. Since the temperature of the medium 3 drawn out of the fluidized layer furnace is high, it is cooled by sending cold water from a supply pipe passage 14 to a jacket 14a, and it can be discharged from the pipe passage 15. Further, since the internal 9 is installed between the diffusion plate 8 and discharge pipe 10, the generation of air columns is eliminated and at the same time it is possible to prevent slagging while holding a small ratio, L/D wherein L for layer height and D for inner diameter D of the device.

That is, the radius of curvature r1 of the plane shape of the bead 10 is made small at the portions between the bolt holes 8 apart from the bolt holes 8 where the fastening force is small, on the other hand the radius of curvature r2 is made large at the bolt fastening portions near the bolt holes 8 where the fastening force is large. Accordingly, the face pressure is made uniform.

Title: Rotor of motor for driving polygon mirror
Inventor: HAYASHI KUNIO
IPC: H02K1/22
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To suppress increase of interval between parts as much as possible even if each part of a motor expands thermally due to temperature rise at the time of driving the motor. SOLUTION: A rotary shaft 41 is fitted with a mirror retainer 48 made of an iron material and located above the fitting protrusion 44a of a mirror supporting member 44 and the mirror retainer 48 is tightened to the mirror supporting member 44 by means of screws 49. Since the rotary shaft is made of stainless steel and the mirror retainer 48 is made of an iron maternal having lower coefficient of thermal expansion than stainless steel, the gap being set between the mirror retainer 48 and the rotary shaft 41 at the time of assembling is decreased as the temperature rises through rotation of the rotor 42. Consequently, the mirror retainer 48 is fitted firmly to the rotary shaft 41 at the time of rotation of the rotor 42 thus eliminating positional shift of the mirror retainer 48.

Title: Automatic answering telephone system
Inventor: ONOZUKA KATSUHIKO
IPC: H04M1/65
Filed: 1994-02-16
Abstract: PURPOSE:To reproduce only a required message by stopping the reproduction of a message according to the detected output of an invalidity detecting means for detecting the invalidity of sound recording of the message. CONSTITUTION:When the sound recording of a message is performed in a recording and reproducing IC 8, a CPU 1 detects the invalidity of that sound recording so that only the valid message can be reproduced in the case of reproducing the message. Therefore, only the required message can be reproduced. When the invalidity of the sound recording of the message is detected, the CPU 1 resets a valid flag provided corresponding to the start address of the relevant message in a sound recording table and judges the presence/absence of reproduction of the message corresponding to the presence/absence of that flag. Thus, when judging the presence/absence of reproduction of the message sound recorded in the sound recording and reproducing IC 8, it can be judged with a simple configuration.
